Not sure if this is relevant to the Mac Mini M1 hardware or to BigSur 11.1 or something else. A ViewSonic VX2476 24-inch full HD IPS screen is attached from one of the two thunderbolt ports to the screen's displayport port.
Also tried with the Hyper terminal app but same problem.
Tried turning off font smoothing via command line but no change.
Screen also has an HDMI and a VGA inputs but haven't tried since I don't have the cable for the former or the adapter for the latter.
What can I try?
Thanks a lot
